TRACE-FASTENING DEVICE.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed December 7, 1906. Serial No. 346.795.

T0 on whom it Wmy concern:

Be it known that I, CHARLES M. LEHMAN, a citizen of the United States, residing at Middlebury, in the county of Elkhart and State of Indiana, have invented new and useful Improvements in Trace-Fastening Devices, of which the following is a specificatlon.

My invention pertains to devices for fastening traces on swingletrees and it consists in the peculiar and advantageous construction hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a view illustrating in elevation a portion of a swingletree equipped with my novel device and also illustrating in transverse section a trace held by the device on the swingletree and further illustrating by dotted lines the position in which the device is placed relative to the swingletree to permit of a trace being placed on or removed from the swingletree. Fig. 2 is a perspective view of the portion of the swingletree bearing the fastening device, the trace being shown by dotted lines. Fig. 3 is a plan view showing the .trace secured through the medium of the fastening device on the swingletree, and Fig. 4 is a transverse section taken in the plane indicated by the line 4 4 of Fig. 3 looking outward.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which A is a swingletree, which is preferably of the well-known conventional form.

B is a trace, which is provided with an eye I) and is otherwise of the ordinary type.

C is my novel device for fastening the trace on the swingletree, and D is the screw which forms a pivot for and effects connection of the fastening device 0 to the swingletree.

The fastening device 0 is formed of one piece of suitable metal and comprises an intermediate portion 0, having a transverse aperture for the passage of screw D and also having a countersink d in its outer side to receive the head of the screw, a trace-retaining arm e, reaching from said intermediate portion 0, and an arm f, which is disposed at a right angle to the retaining-arm e and is preferably of greater length than the said arm e in about the proportion shown in order to afford leverage and in that way render adjustment of the fastening device more easy. At its free endi. 6., its end remote from the intermediate portion cthe arm f of the fastening device is provided with an enlargement 9. This enlargement g is designed to prevent the trace B from slipping inward on the swingletree to a point where said trace is clear of the armf, and it is provided with an extension h, disposed laterally to arm f and designed by bringing up against the side of the swingletree to hold the arm f against downward movement beyond the position shown in Fig. 1.

In practice my novel fastening device is arranged against and connected to the edge of the swingletree, and when it is desired to place the trace on the swingletree the fastening device is swung to the position shown by dotted lines in Fig. 1, so that its retainingarm e lies parallel to the edge of the swingletree, while its arm f extends upright. The trace is then shoved on the end portion of the swingletree and the arm 6 of the fastening device until it rests adjacent to the intermediate portion 0 of the device, when the device is swung to the position shown by full lines in Fig. 1. On this being done it will be observed that the arm f of the fastening device will rest in the eye of the trace and will be retained by the trace against casual move ment away from the edge of of the swingletree, and consequently the retaining-arm 6 will be held in an u right position, in which position it will prec ude casual movement of the trace off the swingletree. To remove the trace from the swingletree, it is simply necessary to position the trace adjacent to the intermediate portion 0 of the fastener and then move the fastener to the position shown by dotted lines in Fig. 1, when the trace may be readily moved off the arm 6 and the end portion of the swingletree.

It will be gathered from the forgoing that my novel fastening device is simple and inexpensive in construction and light in weight and that it is calculated to enhance rather than detract from the finished appearance of a swingletree.

Having described my invention, what I claim, and desire to secure by Letters Patent, is

The combination of a swingletree, and a trace-fastening device arranged to swing vertically alongside one edge of the swingletree and comprising an intermediate portion pivotally connected to the edge of the swingletree, an arm adapted in one position of the device to extend upward from the intermediate portion and retain a trace on the swingletree and in another position of the device to side of the swingletree to hold the arm rest parallel to the edge of the swingletree, an against undue downward movement. arm extending from the, intermediatev portion In testimony whereof I have hereunto set and at a right angle to the retaining-arm and my hand in presence of two subscribing Wit- 5 arranged when said retaining-arm is upright nesses.

to lie parallel to the ed e of the swingletree,

and a lateral enlargeme nt g on said arm, ary CHARLES LEHMAN' ranged to hold the trace against undue in- Witnesses:
